Schae-Lee Olckers’
UFS PhD student and food scientist Schae-Lee Olckers’ research could contribute to a stable supply of good quality wheat and bread, even in the face of climate change.
Follow your passion in order to find your purpose. This is the mantra of food scientist and University of the Free State (UFS) PhD student Schae-Lee Olckers, whose research is set to improve wheat quality by identifying which types of wheat are better able to tolerate stress, and which proteins are most important for producing high-quality bread. 
 
“By grasping this, it is possible to ensure that we continue to have a stable supply of good quality wheat and bread, even in the face of climate change,” says Olckers, who believes wheat is one of the most important food grains in the human diet, and one of the most important staple cereal crops in the world.

Her PhD study, ‘The influence of abiotic stress on gluten protein and baking quality in bread wheat’, under the supervision of Dr Angie van Biljon and Prof Maryke Labuschagne in the Department of Plant Sciences, and Prof Garry Osthoff in the Department of Microbiology and Biochemistry, is investigating how different levels of heat and drought stress – mostly due to climate change – affect the gluten protein composition of high-yield bread wheat.

Olckers is a food scientist at StartWell Foods (Pty) Ltd, a non-profit organisation that produces high-quality extrusion products for feeding schemes around the country. The products help to eliminate stunted growth among children.

Her research focuses on examining different types of wheat and investigating how proteins are affected by stressors like heat and drought, to understand how these stressors impact the quality of bread. She uses new proteomic methods to look at the different proteins in the wheat flour, to gain a better appreciation of how gluten proteins react to stress.

In this study Olckers is able to see how the proteins change in the various wheat cultivars, helping us to understand how the different types of wheat perform in baking, and how the proteins affect the final product.

She collaborates with the International Maize and Wheat Improvement Center (CIMMYT) in Mexico, that releases new wheat cultivars for developing countries. Their aim is to develop wheat cultivars that maintain their quality in different environments.  To investigate the performance and characteristics of the seeds, both in the field and in the laboratory, CIMMYT did the field trials, quality assessment, and supplied the seeds for high-performance liquid chromatography (HPLC) and proteomics analysis. 

Finding ways to adapt to climate change

She believes that understanding how these stressors impact the production of bread-baking quality in wheat will help scientists gain important insights into how climate change affects our food supply. 

“Taking into consideration the current and projected intensifying heat and water deficit stresses, it is crucial to improve the understanding of these phenomena in order to implement new breeding strategies for sustainable wheat quality. This research could help us find ways to adapt to climate change and continue to produce high-quality wheat and bread for people around the world,” Olckers says.

Lecture focuses on how Marikana widows embody the transformative power of art

"When I got the news of my husband is dead, I put my hands above my head, as you see me in this picture. I could not bear the ache in my heart." - Makopane Thelejane

A woman looks down on a canvas covered in thick layers of red, dark shadows falling across her face. A brief moment that captures the silently-devastating aftermath of the Marikana massacre that bled into the lives of 34 widows.

It is this silent trauma that was at the centre of the last instalment of the Vice-Chancellor’s Lecture Series for 2015. “These stories of the Marikana widows are important. It is these stories of silence that live behind the spectacular scenes of the violence,” Prof Pumla Gobodo-Madikizela, Senior Research Professor in Trauma, Forgiveness, and Reconciliation Studies at the University of the Free State (UFS) said at the event.

Panel
The lecture, which took place on Monday 27 July 2015 on the Bloemfontein Campus, took the form of a panel discussing the theme of “Speaking wounds: voices of Marikana widows through art and narrative”. The panel consisted of members from the Khulumani Support Group, including Dr Marjorie Jobson (National Director) and Judy Seidman (Sociologist and Graphic Artist), as well as Nomfundo Walaza, former CEO of the Desmond Tutu Peace Centre.

"Then this dark time came, a dark cloud over me. It made me to have an aching heart, which took me to hospital, from losing my loved one, my husband, in such a terrible manner. " - Betty Lomasontlo Gadlela

Trauma made visible
In a project initiated by Khulumani, the Marikana widows were encouraged to share their trauma through painting body maps – in which the widows depicted their own bodies immersed in their trauma – and narrating their personal stories. Throughout the workshops, the focus always remained on the women. As Siedman put it, “the power of this process is rooted in the participants. The statements of what the participants experienced is what’s important.”

Initially silenced and isolated, this group of women has now moved “into a space where they have become connected to each, and stand up for each other in the most powerful ways,” Dr Jobson said. “Our work is conceptualised in terms of giving visibility and voice to the people who know what it takes to change this country; to change this struggle.”

The transformative power of art and narrative
During her response, Walaza pointed out “how art and narrative can transform traumatic memory and become integrated in the survivors’ life story.” This gives individuals the opportunity, she said, “to step into a space of mutual listening and dialoguing in which people bond together.”

Co-hosted by Prof Gobodo-Madikizela and the UFS Institute for Reconciliation and Social Justice, the lecture series forms part of a five-year research project funded by the Andrew W. Mellon Foundation.
